Upwelling-air distributor for air-conditioning systems

Abstract

An upwelling-air distributor for air-conditioning systems. It comprises two concentric, air-permeable cylinders, an outer cylinder (1) and an inner cylinder (2). The cylinders accommodate one or more diaphragms (10 and 11) in the form of flat rings. The distributor is connected to the ventilating system by an air intake (3) at one end. A pipe (6) is accommodated inside the inner cylinder. The pipe is provided with a butterfly valve (7) and is open at the end remote from the air intake. Air can flow through the pipe except when the valve is closed.

We claim: 
     
       1. An upwelling-air distributor for air-conditioning systems comprising: two concentric air-permeable cylinders, one of said cylinders being an outer cylinder and the other one of said cylinders being an inner cylinder; at least one diaphragm in form of flat rings inside said inner cylinder; an air intake at one end of said distributor for connecting said distributor to a ventilating system; a pipe inside said inner cylinder; a butterfly valve inside said pipe, said pipe being open at an end remote from said air intake, so that air can flow through said pipe when said valve is not closed. 
     
     
       2. An upwelling-air distributor as defined in claim 1, including a swirl-inducing fan inside said pipe. 
     
     
       3. An upwelling-air distributor as defined in claim 2, wherein said fan can be raised and lowered, said fan having blades with an adjustable angle. 
     
     
       4. An upwelling-air distributor as defined in claim 1, wherein said valve is an electrically operated valve. 
     
     
       5. An upwelling-air distributor as defined in claim 1, wherein said valve is a pneumatically-operated valve. 
     
     
       6. An upwelling-air distributor as defined in claim 1, including another diaphragm in form of a flat horizontal ring in a gap between said pipe and said inner cylinder and dividing said gap vertically into two compartments. 
     
     
       7. An upwelling-air distributor as defined in claim 1, wherein said at least one diaphragm has solid peripheries. 
     
     
       8. An upwelling-air distributor as defined in claim 1, wherein said at least one diaphragm has perforated peripheries.
